Harold Camping, leader of Family Radio Worldwide, believed "beyond the shadow of a doubt" the day of judgement was upon us.

He was determined the Rapture - a belief that Jesus Christ will return and take the faithful to heaven ahead of the unleashing of hell on Earth - would begin at 6pm local time in each of the world's regions.

The 89-year-old retired civil engineer from California said he had "absolute proof" of the time and date thanks to the Bible. "Beyond the shadow of a doubt, May 21 will be the date of the Rapture and the day of judgement," he was quoted as saying in January.

I am sure that being wrong with a prediction - not once but twice - such as the end of the world, brands you as a false prophet. We are told in the same book that Harold Camping said "without a doubt showed him that the rapture would begin today -May 21,2011." The Bible clearly tells us what a false prophet is, and how to recognize one.

Deuteronomy 18:20-22 NKJV (20) But the prophet who presumes to speak a word in My name, which I have not commanded him to speak, or who speaks in the name of other gods, that prophet shall die. (21) And if you say in your heart, ‘How shall we know the word which the LORD has not spoken?’— (22) when a prophet speaks in the name of the LORD, if the thing does not happen or come to pass, that is the thing which the LORD has not spoken; the prophet has spoken it presumptuously; you shall not be afraid of him.  read more »
